Urena was optioned to Triple-A New Orleans on Saturday, Andre Fernandez of the Miami Herald reports.
Urena's time with the big league club seemed to be drawing to a close, as the Marlins acquired rotation upgrades in Andrew Cashner and Colin Rea from San Diego this week, and Urena sealed his fate with an eight-run blowup against St. Louis on Friday. Urena will return to New Orleans for now and will probably find himself assigned to the bullpen upon his eventual return.
